Method and apparatus for plotting polygon edges on a pixelized grid

ABSTRACT

Incremental methods of drawing (respectively) polygon edges, wide-line edges, and single-pixel-wide vectors on a pixelized grid. The methods make use of improved, Bresenham-like algorithms for computing the next pixel to be drawn, in which novel decision variables are utilized. The decision variables are designed to be computable in a reduced number of bits. The algorithms and their decision variables permit the use of comparatively simple circuitry for computation.
